Figure 21: MRI of the patient sagittal T2

• Q1:What is that abnormal cord signal and why?
• Extensive abnormal hyperintensity is noted across three levels with a swollen cord at C5-6. There is no reported history of trauma, suggesting potential causes such as spinal cord ischemia, neoplastic involvement, or a demyelinating process. Additionally, there is a posterior disc herniation at C5/6.

• Q2:What is the normal lordotic cervical angle?
• Normal lordosis is maintained between 20-35 degrees.

• Q3:What is normal cervical canal diameter?
• Mean of normal male cervical canal diameter ranges from 16.5 to 21.4 mm Females 15.5 to 20.2 mm
